High power modular drives
16 June 2016
Control Techniques, an Emerson business, has extended its range of high power modular drives. Both its Unidrive M and Powerdrive F300 variable speed drive ranges are now available in the larger frame size 11, providing a flexible method of building compact, reliable high-power solutions.
Paralleled together, Unidrive M can control asynchronous and permanent magnet motors in systems up to 2.8 MW (4,200 hp). The new frame 11 is a 250 kW (400 hp) module that allows system builders to create high power solutions with the smallest number of components, keeping both footprint and costs to a minimum.
Unidrive M offers extremely fast current control algorithms and high switching frequencies. Active Front End (AFE) solutions deliver high levels of torque precision and power quality.
